You can use the show mac-address-table command with the vid and vlan number or in the newer rev of code with the port number if you want.

show mac-address-table vid 2
show mac-address-table port 21

Once in the CLI you need to be in the enable mode. It looks like the command to display by port still requires the vlan ID to used as well. See examples below.

nope-5510-1>enable
nope-5510-1#show mac-address-table vid 1
